Soft-hadronic observables for relativistic heavy-ion collisions at RHIC and LHC

TL;DR

This paper uses relativistic hydrodynamics and statistical hadronization to describe soft hadronic observables in heavy-ion collisions at RHIC and LHC, predicting saturation effects at higher energies.

Contribution

It provides a unified description of soft hadronic observables across RHIC and LHC energies using a combined hydrodynamics and statistical model approach.

Findings

Good agreement with experimental data at RHIC

Prediction of saturation of pion elliptic flow at LHC

Moderate increase of correlation radii at higher energies

Abstract

The relativistic hydrodynamics together with the single-freeze-out statistical hadronization model is used to describe the midrapidity hadron production in ultra-relativistic heavy-ion collisions at RHIC and LHC. At the highest RHIC energy our approach gives a quite satisfactory global description of soft hadronic observables including the HBT radii. With the increased initial energy, from RHIC to LHC, we expect the saturation of the pion elliptic flow and the moderate increase of the correlation radii.
